How is your coolant loss?
How is your coolant loss?
It looks like cylinder 1 fails pretty often on the hg for these. Mine at 250k, no noticeable oil use, I believe is about to need a head gasket because of this cylinder.
I got a 80 dollar cylinder scope tool from harbor freight and put it down in the cylinder it's a little cleaner than the rest, started misfiring on cold and warm restarts. I cleaned the map/maf, egr system/manifold, plugs, pcv replaced etc.. lol I'm certain I'm in for a HG. I'm going to do the injectors at the same time.
Have your cylinder head replaced if you do head gasket. or at least resurfaced since you are only at 125k.
- All of the best to you.
